QI understand the new tax law reverses the rules for alimony, so that the payer no longer gets to deduct payments and the recipient no longer has to pay tax on alimony received. I was divorced in 2016. Does this mean the alimony payments I get are tax-free from now on?

A No. The new rule does not go into effect until 2019, and only for divorces executed or modified after 2018. For divorces after December 31, 2018, alimony payments are no longer deductible nor must the recipient declare the amount as taxable income. The law specifically permits ex-spouses to modify an earlier divorce agreement to adopt the new rule after it goes into effect in 2019. Of course, both you and your ex would have to agree to such a change. If a pre-2019 divorce is not modified, the old rules apply: the payer can deduct payments and the recipient must pay tax on them.
